To all whom, it may concern.-

Be it known that I, GEORGE ROSE, a subj ect of the Queen of Great Britain, and aresident of the city of Glasgow, Scotland, have invented certain new and useful Improvements in Lamps for Burning Mineral or other Oil, of which the following is a specification.

This invention relates to improvements in the construction of lamps for burning mineral or other oil in the form of gas or vapor. In lamps of this class as generally constructed the mineral or other oil to be converted into gas and then burned is contained within a closed tank or vessel, the tank forming the base of the lamp. From the tank the oil is forced to ascend up a stand-pipe or tube to a vaporizing-chamber by the action of compressed air contained in or forced into the tank by a force-pump. In the vaporizingchamber the oil, by the heat of the flame of the lamp, is converted into .gas or vapor, which gas or vapor is conducted from the chamber to the lamp-burner, which is so situated that the flame issuing therefrom plays upon and heats said vapor-chamber.

My improvements over the lamps of this class as heretofore constructed consist in providing improved constructions and arrangementofthepartsof vapor-generatingchambers and means for carrying off any tar or residual carbon which may accumulate in said chambers and their connections, and, further, in providing a vapor-accumulator for the purpose of keeping an even flow of vapor to the burner and to thus conduce to the steadying of the flame.

In order that my said invention may be clearly understood, I have hereunto appended an explanatory sheet of drawings, whereon Figure 1 represents in elevation one form of my improved vapor-lamp. Fig. 2 is a plan view of the vapor-chamber and connections. Fig. 3 is a detail view, to alarger scale, of the combustion-box and drip arrangement, while Fig. 4 is a plan view showing the oil-tank and fittings. Fig. 5 represents in elevation another form of my improved lamp. Fig. 6 is a part sectional plan, to an enlarged scale, of the superheating vapor-chamber of same; Fig. 7, a part sectional elevation, to a larger scale, of

the head of the lamp, and showing the superheating vapor-chamber and casing in section on the line a 00, Fig. 6, while Fig. 8 is a plan view of the head of the lamp. Fig. 9 is asectional view of a modified ring construction of superheating vapor-chamber and made in two halves, and Fig. 10 a plan View of the same, while Fig. 11 shows in section a joint for connecting the two halves of the chamber together. Fig. 12 is a part sectional view of another form of vapor-chamber, made like a tube and having at one end alid or door for cleaning purposes.

On the drawings the samereference-letters indicate similar or like parts wherever repeated.

Referring to Fig. 1, A is the oil-tank, which may be of any suitable construction, and which is provided with a filling-plug a and a cleaning-plug b. It is also provided with a pressure-gage c for registering the air-pressure within the tank. 13 is a small hand-pump for forcing air into the tank; or instead of using a pump the air may be supplied to the tank from an air-compressor or by a fan or otherwise. The pump B may be worked by hand, as shown. The oil to be vaporized and burned is forced from the tank Aup the pipe C, which has a rose at its base, and the rose may, if desired, be protected by wire-gauze So for the purpose of preventing sediment entering the pipe. The oil passes from the pipe 0 through the branch F to the stand-pipe or tube G, a wheel-valve D being provided to regulate the oil-supply. From the tube or stand-pipe G the oil passes into a coil-pipe H, preferably fitted 011 its upper end. This coil-pipe is for the purpose of facilitating the vaporizing process by warming the'oil prior to its passing into the tubular vaporizing- 9o chamber 1, to gently heat the oil, so as to melt any naphthaline crystals, and then to vaporize it later in another part of the lamp. This coil-pipe also steadies the oil-supply. This chamber I is a peculiar construction or 5 arrangement of the usual copper or other metallic vaporizing tubes or channels. As will be seen from the plan View in Fig. 2 and the elevation in Fig. 1, the tubes constituting the chamber are all arranged at right angles to I00 each other, the angles being formed by tubu- For the purpose of carrying off any driplar cross and T pieces, which are provided that is, any tar or residual carbonwhich with easily removable screw-plugs 21 for may accumulate in the tubes or pipes, I procleaning. The warm oil from the coil-pipe vide a drip tube or chamber L, which may II passes first along the tube 1, (which in Fig. be in the form of an enlarged tube, as shown 1 is partly broken away to show the tube 5 at Fig. 1, or it may be a hollow ball, as shown behind it,) thence along the tube 2, (see Fig. at Fig. 3, or it may be of any other equiva- 2,) and thence successively through the tubes lent shape. This drip tube or chamber is 3, 4, and 5. This latter tube 5 is so arranged shown as screwedby a short pipe-connection as to be immediately over or in the center of into the under side of the T-piece forming the top of the flame. From the tube 5 the the junction between the tubes 11 and 12. now vaporized oil passes up a vertical tube The drip arrangement would in all cases be 6, Fig. 1, and then through a return-tube 7, preferably supplied with a small tap or cook placed above the tube 5, thence again through 15 (or a screw-plug may be used) for the puror up another vertical tube 8 and into the pose of drawing off the residual or liquid tar. return-tube 9, placed above the tube '7. The The T-piece 16, forming the support for the tubes 1, 2, 3, and 4 surround the flame and burner 13 and combustion-box K is shown as provide a heating-chamber, while the tubes being used as an auxiliary drip, a small cook 5, 7, and 9, passing through the flame, pro- 17 being screwed into its under side,bywhich videa superheating-chamber. From the tube the tar or residual can be drawn oil. 9 the vapor ascends into an accumulator J, To relieve the strain on the vaporizingpreferably fitted on top of the cross-piece chamber I and to keep the parts steady when forming the angle between the tubes 9 and the lamp is being n1oved,I provide an ad- 0 10, and which is of hollow spherical form, justable bracket M, capable of sliding and as shown, although it might be of cylindrical being clamped in any desired position on the or other equivalent shape.

By having the increased heat sufficient vapor would be tubes 5, 7, and 9 above each other, with the thrown off to keep the flame at its normal vertical connections 6 and 8 between the1n,a height. \Vith the accumulator during such defect very common in vapor-lamps as hereperiodsof lessened vaporization vapor would tofore constructedna1nely, that of flooding be supplied from it to the burner and so tend the lamp from turning on too much oil or to keep the flame steady.

My improved arrangement has a further sagglvantage in being very easily cleaned of 1 20 then, as cleaning-plugs 21 or doors or other lvices can be arranged at each angle for this i-pose. @In the modified. arrangement of lamp shown l Figs. 5, 6, 7, and 8, instead of making the tporizing-chamber I of a number of tubes laced in rectangular formation, I vaporize to oil in a super-healer consisting of a coil.-

oil-supply, and then into the oil warming or heating arrangement II, which is made preferably of three tubes 18, 19, and 20, (see Fig. 8,) joined together at their angles by T cross or knee pieces. In the case of T or cross pieces being used cleaning-plugs 21 are also used. In these tubes the oil gets highly heated and partly vaporized. From the tube: 20 the partly-vaporized oil descends by the? vertical pipe 22, Figs. 5 and 7, into the upper? side (or it may be the under side) of the splitring chamber or coil S. The ends of this: -chamber S are cast solid or plugged up, so that the oil entering at the inlet 22 has to@ pass completely round itbefore escaping by the outlet-pipe 23, and so to the burner 13.} Round the circumference of the chamber screw-plugs s are provided for cleaning'out carbon. I

The split-ring construction of chamber Si while being simple is also effective, for it insures a thorough vaporization of the oil, from its having to pass round the full circuit of the ring or 'coil before reaching the outlet. This construction also allows for expansion'under great heat. With this arrangement of lamp I prefer to make the drip-tube as a hollow chamber 24., constituting the base of the burner 13. This chamber 24 may be providedwith a screwplug 25 for cleaning purposes, and a cook 26 for blowing off tar or residual. The combustion box or casing K is supported on top of the stand-pipe G, and is so made as to surround and inclose the burner and vapor-chamber, and to thus protect them from the chilling effect of the atmosphere. A number of holes f are made, preferably round the lower part, to admit air to support combustion, and if required a small hinged or other door g may be fitted on it to allow of the burner being cleaned.

Figs. 9, 10, 11, and 12 represent tubular box or ring constructions of vapor-chamber, with easily-removable lids for cleaning purposes.

Figs. 9, 10, and 11 show a box-chamber U, made in two halves or parts, the upper part being easily removable and constituting the lid. The parts are secured together by bolts or studs 9. These bolts or studs I prefer to secure at their lower ends in sockets or snugs h, cast on the under half of the chamber, although they may pass right through the chamber and they may have screw-nuts at both ends. To make a tight joint between the halves of the chamber,flanges t' and j are cast or formed on the halves of the ring. The flanges 1,1 prefer to makein the inside of the ring, as shown, as they do not then split or impede the passage of the flame, and the flanges j may be on the outside, or both jointin g-flanges v1 andj may be made on the inside, or both on theinside and outside. The flanges of the upper half or lid are preferably made with a groove in them, (see Fig. 11,) and into this groove fits a circular rib or projection formed on the flanges of the lower half. The

joint is made tight by asbestus or other packing.

In order that the oil may circulate around the ring, a partition or piece K (shown in dotted lines at Fig. 10) is or may be cast or formed in the inside of the ring-box. The oil enters the ring at the inlet 22, and passes out in the form of vapor at the outlet 23 (indicated in dotted lines) and so to the burner.

hen the two parts of the chamber U are unbolted, by unscrewing the nuts the carbon which may have been deposited in the inside can be easily cleaned out.

Fig. 12 shows another form of box-chamber I, which may be used in lieu of the rectangular construction of chamber I, hereinbefore described with reference to Figs. 1 and 2. This chamber'consists of a single tube plugged or cast solid at one end, the other end being formed with a flange Zaround it. To this flange a lid or 'door m is bolted or screwed in a removable manner, so as to enable the chamber to be cleaned out: The lid has preferably a circular ridge n on it which fits into a corresponding groove in the flange Z, the joint being made tight by asbestus or other packing. The oil-inlet is shown at 0 and the vapor-outlet at 19.

Instead of using a single split-ring chamber S, as shown, two or more may be used, and, if desired, the warming-tubes H, Fig. 8, may be replaced by a ring-box or a split-ring chamber, and instead of having two vertical connections 6 and 8, as shown at Fig. 1, for the chamber I, one or more may be used.

Handles Z, arranged one on each side of the tank, may be provided for the easy remo val of the lamp from place to place, as desired.

To start the lamp, naphtha or other oilsaturated waste, or oil only, is put or poured into the initial heating-cup Y, Fig. 1, and the cup turned into the position shownin dotted lines, or into the combustion-box K, Fig. 5, which on being ignited would raise sufficient heat to vaporize the oil in the vapor-chamber.

Although I have only shown the vapor-accumulator J as used with the lamp at Fig. 1, it may also be used on top of the lamp at Fig. 5.

The bolts 9 (shown at Fig. 9) would preferably be iron ones with brass nuts.

My improved lamp may be used for heating as well as lighting purposes, and where it would be desired so to use the lamp the flame would preferably be directed horizon tally into the furnace or chamber to be heated.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that What I claim is 1. A lamp comprising a tank, a stand-pipe, heating-tubes surrounding the flame, a coilpipe connecting the tubes with the standpipe, a superheating-tube connected with the heating-tubes and exposed to the action of the flame, a pipe depending from the super- ICC heating-tube, the branch pipe, the burner, and the combustion-box, substantially as described.
